COMP OSITION FOR AND PROCESS OF MANUFACTURING JOURNAL-BEARINGS.

SPEGIFIGATION forming of Letters Patent No. 248,274, dated October 18 1881.

Application filed January 19,

Be it known that I, LoUIs BASTET, of Brooklyn, Kings county, and State of New York, have invented a new and useful Improvement 5 in Compositions for and Processes of Manufacturing Journal or Axle Bearings or Boxes, of which the following is a specification.

My invention consists, essentially, of a new article of manufacture, forming an axle or jourm nal box for machineryot all kinds, also for car and carriage or wagon axle-boxes generally; and it also consists of a process of making the same.

The said improved journal and axle boxes lime and a solution of alkaline silicate of pot-, ash or soda, which mixture is molded, while in a plastic state, to produce the form or shape desired for the box or hearing, then baked or dried to harden and solidify the material, and then, when desired, saturated with a mixture of melted tallow and crude parafiine to smooth the lime.

The accompanying drawing represents a 2 perspective view of a half journal-box for shafting of my improvement.

In carrying out my invention I mix ground desired proportions, from twenty-five parts of either to one hundred of both, and then mix therewith, also at atmospheric temperature, a solution of alkaline silicate of )otash or soda in suflicientquan it I! t From this paste 1 mold or otherwise shape or form the box or hearing to suit the journal or axle to which it is to be applied,and their dr and harden it b; heat either natural or ar 1- c a rom 36 o L Fahrenheit-to which I prefer to bake the articles in an oven, by which the hardening may be sooner efi'ected, and the heat may be regulated and controlled to better advantage, according to' the judg- 4 5 meat of the operator. The boxes may be used in this condition;

The proportions of the mixture of tallowaud parafline may-be from twenty-five to seventyfive of either to one hundred of both.v

What I claim-and desire to secure by Letters Patent, is-- 1. The herein-described improved article of manufacture, consisting of a journal or axle box composed of a solidified mixture of plumbago, phosphate of lime, and alkaline silicate ofpotash or soda, substantially as specified.
